Pre-tightening device and pre-tightening fixing assembly for building formwork
The invention provides a pre-tightening device and a pre-tightening fixing assembly for a building formwork. The pre-tightening fixing assembly comprises a split fastening device and the pre-tightening device. Threads of split bolts are engaged with arc-shaped ratchets to be clamped and generate resistance, and thus split screws are anchored; the split bolts can be pre-tightened rapidly by operating a pressing wrench and a tightening wrench and cooperating with a pulling plate and a support, operation is easy and rapid, one-man operation can be achieved, and the working efficiency is greatly improved; and the split fastening device is used in cooperation, the size is effectively controlled, the buckle strength is high, the number of parts is small, the machining links are reduced, repeated using can be achieved, the manufacturing cost is low, and environmental friendliness and economy are achieved.
本发明提供一种用于建筑模板的预紧装置及预紧固定组件，其中预紧固定组件包括对拉紧固装置和所述的预紧装置，利用对拉螺栓的螺纹与弧形棘齿啮合卡紧并产生阻力，从而将对拉螺杆锚住，通过操作压紧扳手和拉紧扳手并配合拉升板和支架可以快速预紧对拉螺栓，操作简单快捷，可单人操作，极大的提升了工作效率。配合对拉紧固装置使用，有效的控制了尺寸，卡扣强度高，零部件较少，减少了加工环节，可重复使用，造价低廉，绿色经济。
